The Dolphins cannot seem to keep their kickers healthy.
John Potter, working in place of an injured Caleb Sturgis (groin), left Saturday night’s exhibition game against the Cowboys with a hip injury. He did not return.
Potter appeared to injure himself while connecting on a 26-yard field goal in the first half.
He went immediately to the locker room, leaving Brandon Fields to handle kickoff duties.
The Dolphins went scoreless the rest of the half and didn’t need a kicker. After the intermission, Fields and John Denney were the only specialists to come out of the locker room.
Potter had impressed both in games and practice, and had appeared to turn the kicking competition into a real battle.
Coach Joe Philbin said recently that the competition for right guard remains ongoing, and he apparently wasn’t kidding.
Although Shelley Smith started and played well — particularly in the running game — Dallas Thomas had his chances with the starters, too.
They didn’t go quite so smoothly. He was badly beaten in pass-protection, allowing a free rusher that forced quarterback Ryan Tannehill into an awkward, and potentially dangerous, throw.
It was the second week in a row in which Thomas’ blocking put Tannehill in peril. Tampa Bay’s Gerald McCoy beat him soundly last Saturday, including once that resulted in a strip-sack.
Smith, meanwhile, consistently created running lanes, and consequently the Dolphins’ ground attack had its most production of the preseason. Miami rushed for 93 yards on 17 carries in the first half alone.
THOMAS SITS OUT
Running back Daniel Thomas’ summer of discontent continues.
Thomas, in a fight for survival as a member of the team, missed his third consecutive exhibition game with a hamstring injury.
Mike Gillislee, who presumably is Thomas’ top competition, also sat out the Cowboys game. He also has a hamstring issue.
